[ICOM] PRO III

[Adam Farson]

Hi Dave,

I live "north of the border", so none of this affects me. But it seems that
the new NTIA specs are much more stringent than ITU-R Recommendation
SM328-10 (Spectra and Bandwidth of Emissions). I shall have to look into
this when time permits. For example: It is interesting that the IC-M802,
which is fully compliant with FCC Part 90 and ITU-R, is now no longer
NTIA-compliant.

I have some additional comments:

1. Surely, hams who are also MARS or CAP R/O's will not necessarily dispose
of their amateur HF transceivers, as they can still use these on the amateur
bands.

2. I tend to agree with Mac's observation that many MARS/CAP and USCGA
members will "vote with their feet" on this change.

3. Perhaps the motive is something other than spectrum refarming. To my
knowledge, there has not been any spectrum auction activity in the bands
below 30 MHz. Due to the potential impact on international allocations,
reassignment of HF spectrum is not all that simple.

To get back on topic: A recent check on major dealers' used-equipment pages
did not turn up a single used 756Pro3.

Cheers for now, 73,
Adam VA7OJ/AB4OJ

Adam;

If you go to < https://ntc.cap.af.mil/comm/equipment/equipment.cfm > you can
view all the compliant radios useable in CAP and the reason for the
noncompliance of the formerly compliant ones.
. 
Basically the change that killed ham radio in CAP was the "TX unwanted
emissions". 
The new specification is: 43+10log(Px) or 5 watts = 49.98dB, 50 w = 59.98dB,
100 w = 63dB, 125 w = 63.9dB

Icom specifies 40dB at 100 watts. However if you limit the TX to 5 watts the
radio is in compliance. The limitation is most likely of no consequence but
still a limitation and places the radios in the noncompliant box.

If you are in CAP you will have to wait until next year (2008) when e are
scheduled to receive Motorola Micom II HF stations in quantity. Until then
good luck.

What was the nature of the spec change?

Bob;

A lot of the rigs most likely were used in CAP/MARS service. A recent change
in specifications by NTIA removed almost all ham rigs from use by those
groups. About the only rig still valid is the Yeasu FT-817/ND. Then only
because they are 5 watt rigs.
